Sorry about that, fairly obvious that the backtrace is needed in hindsight. :- ) #0 __GI___libc_free (mem=0xa) at malloc.c:3093 #1 0x000055555558f174 in dvb_file_free (dvb_file=0x5555555a1320) at dvb_file.d:282 #2 0x000055555558edcc in types.File_Ptr.~this() (this=...) at types.d:83 #3 0x0000555555574809 in channels.TransmitterData.__fieldDtor() (this=<error reading variable: Cannot access memory at address 0xa>) at channels.d:144 #4 0x000055555556aeda in channels.TransmitterData.__aggrDtor() (this=...) at channels.d:144 #5 0x000055555556ab53 in D main (args=...) at main.d:33 Which indicates that the destructor is being called before the instance has been constructed.
